SWI NGING DOOR OPERATOR Filed Nov. 1, 1929 2 Sheets-Sheet 2 J. djlfaiyaiz I I I v Moi/"Q410- Patented Mar. 10, V 1931 UNITED STATES SAXTON I. MORGAN, OF ALBANY, WISCONSIN .SWINGING-DOOR OPERATOR Application filed November 1, 1929. Serial No. 404,132.

This invention relates to closure or door operators, and more particularly to an operator designed for opening and closing garage doors.

The primary object of the invention is to provide novel means for operating garage doors from a point remote from the doors and from a point Within the motor vehicle'about to enter the garage, thereby eliminating the l necessity of the operator of the vehicle getting out of his automobile to open the doors.

An important object of the invention is to provide an opener of this character which will hold the doors in either their open or closed positions, eliminating any possibility of the doors being moved to their closed positions, by wind pressure.

With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of pa-rts and in the details of construction hereinafter described and claimed, itbeing understood that changes in the precise embodiment of the invention herein disclosed, maybe made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a sectional view through a building illustrating a door operator constructed in accordance with the invention, as

installed therein. 7

Figure 2 is an elevational view of the operating mechanism.

Figure 3 is an enlarged elevational view disclosing the operating mechanism.

Figure 1 is an enlarged detail view of a turn buckle forming a part of the operating device.

Figure 5 is a fragmental detail view illustrating the construction of the spring securing link. v

Figure 6 is a sectional View taken on line 66 of Figure 3.

' Referring to the drawings in detail, the building or garage is indicated generally by the reference character 5, the hinged doors thereof being indicated by the reference character 6, the doors being mounted so that they will swing in horizontal'planes.

' The operating device employed in operating the doors 6, includes a bolt 7 which is positioned in the ceiling of the building, the bolt extending through the supporting memher 8, which is formed with a flange 9 that rests flush against the ceiling. The bolt 7 provides a support for the bar 10 which is pivotally mounted on the bolt to rotate therearound, the ends of the bar 10 being formed with openings, the opening at one end of the bar receiving one end of the cable 11 which passes over the pulley 12 secured to the inner surface of the wallof the building, for

purposes to be hereinafter more fully described.

At the opposite end of the bar 10 is'a pin 13, that is provided with a shoulder so that the same may rest on the upper surface of the bar 10, as clearly shown by the drawings. Supported on the pin 13 is a connecting rod 14 which hasits opposite end pivotally mounted on the pin 15 depending from the sliding block 16, which in turn is mounted on the supporting rod 17, to move longitudinally thereof. Brackets 18 are secured to the coiling by means of the bolts 19, the brackets '18 being provided with openings to receive the ends of the rod 17 to support the rod in spaced relation with the ceiling to permit of sliding movement of the block 16.

A cotter key extends through an opening in the pin 15 and engages the washer 20 that rests against the connecting rod 1 1, to hold the connecting rod in position. lhe reference-character '21 designates a pinwhich is of alength to accommodate the turn buckles'22 and '23 that are shown as positioned thereon, there being provided a cotter key 24 which is passed through an opening in the pin 21 to hold the turn buckles in position on the pin 21.

These turn buckles 22 and 23 have connection with the rods 25 that have right angled forward ends 26 extended through the members 27 that are bolted to the doors. Thus it will be seen that due to'this construction the rods may be adjusted with re-- spect to the pin "21 and block 16, to the end that the closing of the doors will be insured.

Mountedon the pin 13, is a link 28 which is formed with a hook 29 at one end, and an building, as at 32. The opening in the link 28 accommodates one end of the operating cable 33, thatipasses over the pulley34 secured to one side of thebuilding, and through an openof being supplied with a ring 35 to be gripped by the operator of the doors, to facilitate the operation of the device.

It might be further'stated that the pulley 34? is supported by the post 36'that isheld in the ground surface, at a point in front of the building, the position of the post being such that a personapproaching the building or garage in a motor vehicle may pull the cable 33 oausing'the doors to swing open to allow the driver of the'vehicle to drive into the building. 7 WVhenth'e cable 33 is pulled, it is obvious tha-tthe bar will swing in the direction of the arrows in Figure 1, until the end of the bar 10 towhich the rod 30 is connected, swings inwardly past dead center, whereupon the spring31 snaps the arm to a position to bring the stop 37 into engagement with the rod 17, preventing further movement of the bar 10. ,It is obvious that with'the' elementsof the operating device in this position, the doors will be heldin their open positions against closing under wind pressure. When it is desired to move the doors to their closed positions, the cable 33 is again pulled with sufiicient force to move the bar 10 past dead center, with the result that the spring 31.w ll 40 move the bar to its position as shown in full lines in Figure 3 of the drawings, returning the doors to their closed position.

Should it be desired to close the doorsfrom a position within the building, the cable 11 is pulled which movement pulls the bar 10 past dead center, allowing the spring to throw the bar to a position asshown in full lines in Figure 1.

I claim: V r 1. A-door operatorcomprising an operating bar pivotally supported intermediate its ends, a movable block, rods connected with the movable block and having connection with the doors operated by the device, means 6 for transmitting movement of the bar to the rods, and resilient means for holding the ends of the bar past dead center to secure the doors in their open or closed position.

2. A door operator comprising an operating bar pivotally supported intermediate its ends, a supporting rod, a block mounted for sliding movement longitudinally of the supporting rod, a rod connecting the block and one end of the bar, rods connected with the block to move therewith, the last mentioned ing in the front wall of the building, where i it passesover the pulley 34', the free end there-' rods having connection with the doors operated by the device to move the doors to t eir open or closed positions, and means for holding the ends of the bar past dead center to secure the doors in their open or closed position.

3., A door operator com rising an operet ing bar, means for pivota ly supporting the bar intermediate the ends of the bar, a sliding block, a rod connected with one end of the bar, said rod'being connected with the bflf and block, rods connected with the block and having connection with the doors to be operated by. the device, a link mounted at one end of the bar, a rod connected with the link and having connection with a spring, said spring adapted to move the rod to hold the bar in its positions of adjustment, and means for open ating the bar. 1 Ti 4. A door operating device including a bar pivotally supported intermediate its ends, Q sliding block, a rod connecting the sliding block with one end of the bar, a spring men} ber, means for connecting the spring member with the bar to move the bar and rod, rods connected with the block and having pivotal connection with the doors operated by the device, and manually controlled mea'nsfor mov ing the bar to operate the rods. 5. p A door operating device including a. bar, pivotally supported intermediate its ends,a block slidably mounted adjacent to the bar, means fortransmitting movement of the bar to the block, means for transmitting move ment of the block to the doors operatedby f the device, means for moving-the bar to open or close the doors, and resilient means for re 'stricting movement of the bar under normal conditions.

In testimony that I claim the foregoing as. us my own, I have hereto afiixed my si nature.
